CLARENCE C. LONGARD, OF HALIFAX, CANADA. A

HEATER.

SPECIFICATION forming part 0i' Letters :Patent NO. 700,791, dated May 27, 1902. Application filed October 24, 1901. Serial No. 79.872. (No model.)

To all 1072/0771/ it ntrty concern:

Be it known that 1, CLARENCE C. LONGARD,

a citizen of Canada, residing at Halifax, in

the Province of Nova Scotia and Dominion of Canada, have invented new and useful Improvements in Heaters, of which the followmental cone-shaped water-chamber, which inv addition to holding the water at a pointwhere it is surrounded by the iire in the fire-pot,with a view of accelerating the heating of the water and increasing the capacity of the heater, is adapted to support the fuel and prevent the escape of same when the grate below it is at rest, as well as when said grate is actuated, and is also adapted to deiiect the ashes away from the center, and thereby prevent the collection of clinkers between its base and the grate, at which point they would be liable to interfere with the free movement of the grate.

With the foregoing in vmind the invention will be fully understood from the following description and claim when taken in conjunction with the'accompanying drawings, in which- Figure 1 is a diametrical section,on line 1 1 of Fig. 2, of the lower portion of a waterheater constructed in accordance with my present invention; Fig; 2, a section taken in the plane indicated by the line 2 2 of Fig. 1, and Fig. 3 a plan view of the type of fixed grate which I prefer to employ.

Similar letters of reference designate corresponding parts in all of the views of the drawings, referring to which- A is the water-receiving chamber of my improved heater, which, as usual, surrounds the re-pot and is disposed on a suitable base B.

C is the fixed grate, and D is a rotary grate arranged above the fixed grate. The fixed grate may be secured in the surrounding base B in any approved manner, although I prefer to provide it with depending pins a, which are seated in apertured lugs l) on the base for the purpose. It may also be of any construction suitable to the purpose of the present invention; ibutl prefer to construct it after the manner shown in my aforesaid patent-that is, with aA central opening c and slots rl, which radiate from said opening and are of even width throughout in order to prevent ashes or clinkers from jamming in them when pushed toward the opening c by the operation of .the rotary grate. The rotary grate is preferably arranged on antifrictiogrollers e, mounted in short standardsf, ris-y ing from the fixed grate, and is held against casual lifting or rising by antifriction-rollers g, journaled in suitable housings h, attached to base B. Said rotary grate is also of the same construction as the rotary grate of my patented construction -t`. e., it has an opening t', one wallj of which traverses the upper surface of the fixed grate in a curve which gradually approaches the opening c in said fixed grate, segmental bars 7c, and segmental openings Z between the bars. The fuel in the fire-pot rests Von the said bars k of the rotary grate, and hence it follows that when the said grate'is rotated inthe direction indicated by arrow, through the medium of the shaft m, and vthe pinion 'n intermeshefl with the gear p at the under side ofthe grate, the clinkers and ashes which do not pass through the openings l in the grate will fall through the opening rl of the same upon the bars of the fixed' grate, over which they will be pushed :by the cam action of the wall j of the-opening in a direction approaching the lcentral opening c: vIncident to such movement the line ashes will'obviously fall through the slots d 'of the fixed grate, while the clinkers and large ashes will be carried to the opening c, through which theywill drop into the ash-pit.

-E is my improved supplemental waterchamber, which is connected to a conduit r and also `to a conduit s. The conduitr may be'carried to the chamber A when it isdesired to utilizethe chamber E to"accelerate the heating of water in said 'chamber A, or od to a point at which it'is desired-to use heated water. The conduit s may .be provided with a T-coupling t or otherwise oonnected to a conduit t', leading to chamber A, and another conduit t2, leading from a source IOO of supply, as desired. The chamber E is located in the center of the tire-pot, where it will be surrounded by the re, and consequently it willgreatlyassist in the heating of water, and thereby materially increase the capacity of the heater. It is also located immediately above the rotary grate and in line with the central opening therein and is of cone shape, with its reduced end uppermost, as illustrated. By virtue of this latter it will be observed thatin addition to heating Water and increasing the capacity of the heater the supplemental chamber will permit the free escape of ashes through the opening e', and yet will serve to support and prevent the escape of fuel when the rotary grate D is actuated as well as when itis at rest, and will also serve, when the grate D is rotated, to deflect the ashes `away from the center, and thereby prevent the collection of clinkers adjacent to the base of the chamber, at which point clinkers would be liable to be jammed between the chamber and rotary grate and interfere with the free movement of the latter.

While my improved supplemental waterchamberE is calculated, as stated, to increase ,the capacity and improve the efticiency and durability of those water-heaters in which it is embodied, it obviously adds but little to the cost of production-of the heaters, which is an important advantage.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1sy A water-heater comprising a re-pot, a grate atthe base of the fire-pot, provided with a large, central opening, the hollow, coneshaped, combined water-chamber and fuel support and deflector arranged in the center of the fire-box with its reduced end uppermost and its lower endso arranged with respect to the central opening in the grate as to permit the escape of ashes and prevent the escape of fuel through said opening, a watersupply pipe connected t0 the wall of the heater and the combined water-chamber and fuel support and deiiector, and a dischargepipe also connected to said Water-chamber and fuel support and deilector and the wall of the heater.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CLARENCE o. LoNeARD.
